The set cycle time function block provides a fixed cycle time
for processing the circuit diagram and the function blocks.
Wiring a set cycle time function block
The ST set cycle time function block is integrated in the circuit
diagram as a coil.
Figure 131: EZD circuit diagram with enabling of set cycle time
function block.
Parameter display for set cycle time:
The parameter display is used to modify the set cycle time, the
minimum on time and the enabling of the parameter display.
Time range
Inputs
The function block input
>I1
can be assigned the following
operands:
• Constants
• Markers MD, MW, MB
• Analog inputs IA01 to IA04
– IA01: terminal I7
– IA02: terminal I8
J
To prevent unpredictable switching states, use each coil of
a relay once only in the circuit diagram.
